A coin is weighted equally. Calculate the probability of getting exactly 3 heads or 4 heads in 4 tosses of the coin. (Hint: One method creates a sample space)... Select one: a. 6/15 b. 3/8 c. 5/16 d. 1/4

If you know the names of the remaining seven students in the spelling bee, what is the probability of randomly selecting an order and getting the order that is used in the spelling bee? P(selecting the correct spelling bee order) = %3D (Type an integer or a simplified fraction.)

The accompanying table describes results from groups of 8 births from 8 different sets of parents. The random variable x represents the number of girls among 8 children. Complete parts (a) through (d) below. Click the icon to view the table. C a. Find the probability of getting exactly 6 girls in 8 births. (Type an integer or a decimal. Do not round.) b. Find the probability of getting 6 or more girls in 8 births. (Type an integer or a decimal. Do not round.) c. Which probability is relevant for determining whether 6 is a significantly high number of girls in 8 births: the result from part (a) or part (b)? O A. The result from part a, since it less than the probability of the given or more extreme result. O B. The result from part a, since it is the exact probability being asked. O C. The result from part b, since it is the complement of the result of part a O D. The result from part b, since it is the probability of the given or more extreme result. d. Is 6 a significantly high number…

Determine the probability of obtaining a total score of 6 or 7 on a single throw of two dice. The probability is. (Type an integer or a simplified fraction.)

Kaolin is taking a multiple choice math test. Each question has seven presented answers, but only one is correct. If Kaolin guesses randomly for each of the nineteen questions the test has, determine the probability that Kaolin gets at most one question correct. A. 618719 B. 25719 C. (190) +(191)719 D 61825719 E. (61)(191)719

For Parts A, B, and C, use the experiment below. Show all work. Two fair six-sided dice are rolled. Part A: How many outcomes are in the sample space of the experiment? Part B: What is the probability the sum of the two dice will be greater than or equal to 10? Part C: Laura and Bethany want to decide who fills the car with gasoline for their upcoming trip. Laura will fill the car if the sum of the dice is greater than or equal to 10, and Bethany will fill the car if the sum of the dice is less than 5 If the sum of the dice is any other value, the result is discarded. Does this method provide a fair way to decide who fills the car with gasoline? Provide a supporting explanation.
